Modulated phases in a three-dimensional Maier-Saupe model with competing interactions [PDF]

open access: yes, 2017
This work is dedicated to the study of the discrete version of the Maier-Saupe model in the presence of competing interactions. The competition between interactions favoring different orientational ordering produces a rich phase diagram including ...

Surfactant‐Enhanced Electrospun Nanofiber Filters for Efficient Viral and Bacterial Inactivation

open access: yesJournal of Applied Polymer Science, EarlyView.
In this work, electrospun polyacrylonitrile (PAN) nanofibrous filters functionalized with surfactants (CTAB, CPC, and SDS) were developed for air filtration applications. The PAN nanofiber mats enable efficient particulate matter capture while simultaneously providing antimicrobial and antiviral activity against bacteria (E. coli and S.

Improving Oxygen Barrier Performance of Polylactide Film by Using Bleached and Unbleached Nanocellulose From Grape Pomace

open access: yesJournal of Applied Polymer Science, EarlyView.
Bleached and unbleached nanocelluloses were produced from the exhausted grape pomace and applied as coatings on PLA substrates for sustainable food packaging. Unbleached nanocelluloses were more hydrophobic and amorphous than bleached ones. The resulting bio‐based bleached nanocellulose‐coated PLA films showed a 68% reduction in O2 permeability ...

An overview of the postcranial osteology of caecilians (Gymnophiona, Lissamphibia)

open access: yesThe Anatomical Record, EarlyView.
Abstract Caecilians comprise a relatively small (~220 species) group (Gymnophiona) of snake‐like or worm‐like, mostly tropical amphibians. Most adult caecilians are fossorial, although some species may live in aquatic or semi‐aquatic environments, either as larvae or adults.

Several occurrences of osteomyelitis in dinosaurs from a site in the Bauru Group, Cretaceous of Southeast Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract This study investigates the occurrence of osteomyelitis in non‐avian dinosaurs, focusing on the Ibirá locality, a site with a high incidence of this pathological condition. We analyzed six new osteopathic sauropod specimens from the Upper Cretaceous of Brazil.

Histovariability and fossil diagenesis of Pissarrachampsa (Pseudosuchia, Notosuchia, Baurusuchidae) from the Upper Cretaceous of Southeast Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract Notosuchians were key components of western Gondwanan Cretaceous ecosystems in terrestrial predator niches and exhibited remarkable taxonomic and ecological diversity. Previous research has explored their physiology, metabolism, and histology, revealing varied growth patterns and life history strategies.

A produção científica em empresas familiares: um enfoque conceitual

open access: yesRevista de Administração Pública, 2011
Uma das principais dificuldades para a compreensão das pesquisas em empresas familiares é a ausência de consenso sobre uma definição stricto sensu, sendo as existentes baseadas em diferentes perspectivas e critérios.
